Abstract
The study examines the impact of interest rate differential and exchange rate movement on the dynamics of Nigeria’s international private capital flows from 2010Q1 to 2019Q4. It uses the interest rate parity theory and the Markov Switching Time Varying Transition Probability Modelling approach. Findings show that interest rate differential does not explain the dynamics of aggregate capital and Foreign Direct Investment (FDI) flows, but significantly explains Foreign Portfolio Investment (FPI) flows. Also, Movement in real exchange rate is significant in explaining outflows and inflows in FPI, and inflows in FDI, but neutral to aggregate capital flows. The study concludes that deviations from interest rate parity provides opportunities for interest rate and currency arbitrage in Nigeria but using aggregate capital flows mask this evidence. The study therefore recommends that the CBN should focus on exchange rate stabilization policies, so as not only to discourage FPI reversal but to also enhance FDI inflow. This can be done by putting in place foreign reserve accretion measures to boost the ability of the CBN to defend the Naira. The new policy initiative on remittances is a right step in the right direction as it could boost external reserve.
